Construction of Mini Dal Mill
This mini dal mill is simple in castration & easy to operate& Maintains. it consist of horizontal tapered Roller the rolleris covered with emery coating surrounded by screen through whichhusk powder is discharged. The shelled dals pass through aspiratingfan on oscillating sieve unit where appropriate grading of dals isdone.
The vibratory sieves are provided with different size holes tomatch the requirements of the type of dal being processed. Thevibration are included b a cam operated link which is mounted on acounter shaft ( Motor Derived Shaft )
With this mini dal mill jas enterprises is provided paddle typescrew mixer in all Mild steel construction with worm shaft.
Process of mini dal mill
Process of de-husking is doing in two major steps. In the firststep the cleaned and size graded grain are scarify followed by oiladdition and sun / mechanical drying. In the second step, theremoval of husk and splitting into two cotyledons is doing bypassing the material through versatile dal de-husker. Thisde-husker gives 2-4% higher yield of good quality Dal, than thetraditional Dal mill. This method developed by Jas Enterprises isless laborious, requires less time and reduces losses duringde-husking. One of these methods developed and ready forcommercialization is ''MINI DAL MILL''. The technical up gradation& cost economics of the ''MINI DAL MILL combined withfacilities of Grader cum Cleaner can prove to be a boon to thefarmers. This unit installed near the farm itself. Process on Dalmill Cleaning and grading: This unit consists of a vibratoryinclined sieve, hopper, grain collector, waste collector and motor.The vibratory sieves are providing with different size holes tomatch the requirements of the type of Dal being process. Thevibrations are inducing by a cam-operated link, which is mounts ona motor driven shaft.
Pitting Process For Mini Dal Mill : -
An emery roller machine is use to obtain cracking and scratchingof clean dal passing through it. For loosening, the husk tofacilitate the subsequent oil penetration this is required.Gradually the clearance between the emery roller and cage (housing)is narrow from inlet to outlet. Cracking and scratching of husktakes place mainly by friction between dal and emery as thematerial is passing through the narrowing clearance. During theoperation, some of the dal are de-husk and split which are separateby sieving.
Pretreatment with Oil & Water :-
A screw conveyor allows passing the scratched or spittedmaterial through it and mixing of some edible oil like linseed oilis complete. The linseed oil is use at the rate of 1.5 to 2.5kg/tones of dal . These are keeping on floors for about 12 hours todiffuse the oil.
Conditioning : -
dal are condition by alternate wetting and drying. Moisture(3.5%) is adding to the dal after sun drying for a certain periodand tempering is doing for about eight hours. The grain is dry inthe sun again. By allowing water to drop from an overhead tank onthe dal , which are passing through the screw conveyor addition ofmoisture to the dal , are achieving. Until all dal are sufficientlyconditioned the whole process of alternate wetting and drying iscontinued for two to four days. dal are finally dry to about 10 to12% moisture content.
De-Husking and splitting: -
For De-husking of conditioned dal emery rollers called as Gotamachine are used. In one pass or single operation, about 50% of dalare de-husked. De-husked dal are splitting into two parts.De-husked split dal are separate by sieving and the husk isaspirate off. Un-split de-husked dal and tail dal are again de-huskand milled in a similar way. Until the running dal are de-huskedand split of the whole process is repeated two or three times.
Pre Milling of dal :-
To obtain best results during de-husking and splitting of dal inthe Dal de husking machine in Jas brand mini Dal mills, latestmodel improved version, pre milling including grading of dal sizewise is very essential. The raw dal are first clean of dust, chaff,stones and other extraneous materials. Sieves grade cleaned dal ordal graded and soaked in water in cement''s tanks having 6" depth.Height of dal soaked be 5" and the water level should be 1" abovethe dal . Soak dal are taken out of the water after specific timeand put on the sieve. Swollen dal which do not pass through sieve(from which un-swollen dal earlier passed through the same) areready for heaping in shade whereas the dal which pass through thesame sieves. Then these dal are ready for heaping in shade. Degreeof happing of swollen dal in shade should be 30 to 40. This processshould be continuing until the dal are swill to the desired extent.There after the dal are in thin layers in the open sun drying.Duration of sun drying of dal vary according to weather conditionprevailing at the time of processing. After sun drying, the dal areagain heap in shade so moisture contents in the dal may becomeuniform as need in them for de-husking. Then the dal are gradedagain fed in to the dal de husking machine in Jas Mini Dal Mill ingraded lots to achieve he best results with minimum brokenness. Forthe guidance of the entrepreneurs, the process of details ofpre-milling of dal after proper cleaning is show here after in atabulated chart.
